江西省稻米中总砷和无机砷含量的测定与分析
Determination and Analysis on Total Arsenic and Inorganic Arsenic in Rice of Jiangxi Province
摘要
Abstract
The contents of total arsenic and inorganic arsenic in 100 rice samples which were collected from 10 cities of Jiangxi were determined by inductively coupled plasma mass spectrometry ( ICP﹣MS) and high performance liquid chromatography﹣inductively coupled plasma mass spectrometry ( HPLC﹣ICP﹣MS) , respectively. The results showed that the method had good linear relationships with a correlation coefficient of more than 0. 999 3, and the determination of total arsenic and inorganic arsenic contents in reference material for rice flour also showed a better result. The total arsenic contents of 100 rice samples varied from 0. 045 to 0. 382 mg/kg, with an average of 0. 170 mg/kg; the inorganic arsenic content varied from 0. 000 to 0. 180 mg/kg, with an average of 0. 067 mg/kg. The results of SPSS analysis of variance showed that, there are significant differences in the contents of total arsenic and inorganic arsenic among various cities of Jiangxi. The results displayed that the content of As3+ in rice is relatively high, account﹣ing for about 90% of inorganic arsenic content. Results of USEPA health risk assessment showed that the exposure of inorganic arsenic content in rice in Jiangxi province has no risk to human health.关键词
